In religion, you're supposed to be somehow in touch with something deep and full of mysteries.

You ask: what is the meaning or purpose of life? I can only answer with another question: do you think we are wise enough to read God's mind?

The greatest unsolved mysteries are the mysteries of our existence as conscious beings in a small corner of a vast universe.

If you want to have a program for moving out into the universe, you have to think in centuries not in decades.

A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible. There are no prima donnas in engineering.

Technology must be guided and driven by ethics if it is to do more than provide new toys for the rich.

The idea that global warming is the most important problem facing the world is total nonsense and is doing a lot of harm.

Unfortunately the global warming hysteria, as I see it, is driven by politics more than by science.

In the end it is how you fight, as much as why you fight, that makes your cause good or bad.

So long as you have courage and a sense of humor, it is never too late to start life afresh.

Technology is a gift of God. After the gift of life it is perhaps the greatest of God's gifts. It is the mother of civilizations, of arts and of sciences.

Words cannot express love. Only thoughts of love born in silence can do that.

People change. Sometimes I think they don't know they're changing until it's already happened, though. You get so used to being one person, it's weird when you wake up and everything is different.

The beauty is that through disappointment you can gain clarity, and with clarity comes conviction and true originality.

If many have their turns to rule, ... this will encourage all men to advance Righteousness and that the Commonwealth will hereby be furnished with able and experienced men, fit to govern.

All pasts are like poems; one can derive a thousand things, but not live in them.

In life, the first act is always exciting but it is the second act - that's where the depth comes in.

Virtue has its own reward, but no sale at the box office.

My dancing days are past.

I do my very best to not allow external trends or zeitgeists to feed into what I'm producing.

I don't presume to think I'm great at anything.
